Side pumped continuous wave and quasi-continuous Nd: YAG laser. The threshold and output power formula of side pumped CW Nd: YAG lasers have been derived out from the four lever rate-equations.

侧面浦的连续和准连续Nd:YAG激光器从浦光与振荡光空间分布相关的四能级速率方程出发,推导出连续运转的激光输出特性。

An explicit analytical solution of the threshold pump power of the laser has been derived based on rate equations which contain the attenuation coefficients of the pump and laser radiations as well as the major contribution of the re-emission of the upper level atoms to the pump wave by using the analytical solutions. An analytical solution of the minimum fiber length required for the onset of the oscillation is presented. In addition, the analytical solutions describing the variations of the density of the pump radiation and upper laser level population along the fiber length have also been given.
